Application nea september 22.1892. aenewedJuiy 1 1901. serrano. 67,010.(Nq meer To all whom it may concern:

Be it known that I, JOHN H. STONEMETZ, al citizen of the United States,residing at Brooklyn, in the county of Kings and yState of New York,have invented anew and useful Improvement in Printing-Presses, ofwhichthe following is a specification. y y

The aim of this invention isto improve the details of theprinting-machine shown in Letters Patent granted to `1ne Januaryv 3,1888, No. 376,053; and to this` end the invention consists of the devicedescribed and claimed in this specification and illuslrated'in theaccompanying drawings, in which- Figure 1 is a side elevation of enoughof a machine to illustrate my improvements, Fig. 2 is asectionaldiagrammatic elevation. Figs.

' 3, 4, and 5 are details of the inking mechanism of the carriage.VFigs. 6, f7, and 8 are details of the pawl mechanism used in theintermittently-operating delivery device, and Fig. 9 is a detail of the'cam Vactuating lthe brake used in the feeding mechanism.

The driving mechanism for moving the impression-cylinders and the waythe impression-cylinder carriage is mounted to slideon the frame havebeen omitted, as the same are not necessary to a full understanding ofthis v Case.

Referring to the 'drawings vand indetail, AV and B represent ythe, two,yreciprocating img,

y pressioncylindefs, and Ojand D the' form'-n beds, `with whichsaidcylinders are adapted to cooperate. The cylinders Aand B may bermounted in any suitable carriage or framing,

The i011 Rfminwhieh' the web is ieu, is mounted above theform-beds",'a`s shown.y

. From rollF lthe web is led around the rollers 4,5, and 6, which arecontinuously driven, to i slowly unwindl the web from the `r.ollthen l,around the'looping-roller 7, which is mounted in arms 8, which arecarried by arms 9, which have weights 10, which arms 9 are journaled onthe shaftf11,.and then'the web passes around the roller 12, which isloosely journaled in the main framing, as shown, and with which roller12 a brake 18 coperates.

From the roller 12 the web passes to the roller 14, mounted at the endof the press, which roller 14 is continuously driven, for a purposehereinafter described. From the roller 14 the web passes around guide15, carried by the carriage,`around the impression-,cylinder A, aroundguide 16, also carried by the carriage, across the machine to the roller17which is mounted atythe other end of the press and is alsocontinuously driven lback to the guide or` bar 18, carried by thecarriage, around the impression-cylinder B, around guide 19, between therollers 2O and 21, which may be also continuously driven, to and betweenthe intermittently-operating delivery-rollers 22 and 23. By this passageof the web it will be seenthat the same will be printed. as in myLetters Patent before referred to. From the rollers 22 and 23 the end ofthe webis intermittently delivered over guide 24 between the L knives 25and 26, the upper knife 26 of whichy may be reciprocated by av mechanismsuhstantially as shown in Letters Patent to. Kid- 'y der, No; 224,440,dated February 10, 1880, and from the knife the sheet is' passed on to`the continuouslyrunning tapes' 29, which pass over the pulleys 27 and28, whereby the sheet is brought up. against a "suitable stop and isthen tucked between the folding-rollers 30 by the blade 3l, and then iscarried from the roller 30 by suitablevtapes (not shownlover the rollers32 and33,an d'is thentucked by the knife 34 betweensaid folding-rollers,and is then delivered byQiiy 35 I down on the slowly-runningdeliverytap'es 50, which pass around the, rollers 36 and'37.A

Itis not thought necessary to show the de-A tails of the knife-operatingmechanism orof A the folder more atV length the 'only novel point inregard to the folder being'its peculiar y,

relationwith regard to the beds-fthatis, the

folder is placed substantially under one of the beds, whereby. space iseconomized andmthe machine made very compact.

Mounted at each end of the frame is an ink i fountain G, and from thesefountainsink is I taken by the ductor-rollers 38, which are suit` ablyoperated from the shafts 39 and deposited upon the drum-cylinders 40,and from the drum-cylinders 40 the ink is carried by the t icomposition-rollers 41 and 42 to the drumcylinders 43 and 44, which arearranged, as shown, at the outer end of each bed.

The usual gearing, consisting of racks R and thegears S, mounted on theside of the impressioncylinders, is used to keep the cylinders inregister with the beds.

Arranged on each side of each impressioncylinder is adistributing-roller 470, which is positively rotated from the gear S bymeans of intermediates 45 and 46, as shown, and coacting with each ofthese distributing-rollers is a plurality of formerollers, as 48 and 49.Thus there are two form-rollers and a distributing-roller on each sideof each impression-cylinder.

The gearing for driving this various mechanism maybe arranged asfollows: A drivingshaft 51 is arranged in the main frame, and on thisshaft is arranged a pinion 52, which meshes with and drives gear 53, andattached to the gear 53 is a bevel-gear 54, which meshes with and drivesbevel-gear 55, arranged on the parallel shaft 56, as shown. Alsoarranged to turn with gears 53 and 54 is a cam 57, engaging which is ayoke 58, which has suitable rollers 59 and 60 bearing on the sides ofthe cam, and this yoke connects to a suitable bell-crank lever 61, whichhas a suitable toothed segment on the end thereof, which meshes with andthereby oscillates pinion 62, which pinion 62,by means of aratchetmechanism hereinafter described, intermittently imparts motion in onedirection to gear 63, which gear 63 drives the pinion 64, and therebythe gears 65 and 66, whereby the delivery-rollers 22 and 23 areintermittently turned to deliver the web from the press. Also arrangedon the shaft 56 is a bevcl-gear67, which meshes with anddrives gear 68,fast on shaft 6.9,which shaft 69 carresa bevel-gear 100, and by means ofthis bevel-gear 160 and another bevel-gear 101, arranged on the shaft ofthe roller 5, the rollers 4, 5, and 6 are continuously turned to slowlyunwind the web, the rollers 4, 5, and 6 being geared together, as shown.From the gear on the roller 4, by means of a suitable intermediate 102and gears 103 and 104, the rollers 20 and 21 are positively andcontinuously turned. Also mounted on the shaft 56 is la cam 69, whichhas suitable depressions 690, and engaging this cam is a yoke 70, which'carries a roller 71, and this yoke 70 connects to an arm 73 on theshaft of the brake 13, anda suitable spring 72 is arranged, as shown, soas normally to throw the brake olf, but the cam will tend to keep thebrake tightly against the roller 12. Arranged near the ends of the shaft56 are bevel-gears 74, which mesh with and drive pinions 75, mounted onshafts 750. Also arranged on each of these shafts 750 is a bevel-pinion76, which meshes with and drives a bevel-pinion 77, and by, means ofgearing, as 78, 79, 800, 80, and 81, the inking mechanism at each end ofthe press is positively turned. From this gearing gears 87 are alsoturned, and on the ends of the shafts of these gears 87 are are 'rangedsuitable eccentrics 88 and connections whereby the ductor-rollers 38will be vibrated at the proper time to take ink from the fountains G anddeposit the same' on the rollers 40. Near the top of each ofthe shafts750 is arranged a bevel-gear 82, and by means of bevel-pinions 33, 84,and 85 these bevel-gears 82 continuously rotate and drive the roller 14or 17, as the case may be. Arranged on the ends of the shaft 56 areslotted crank-arms 90, and by means of suitable connections 91 andratchets 92 the rollers of the ink-fountains G are slowly turned in theusual manner.

Referring now to Sheet 3 for a specific description of the inkingmechanism carried by the carriage, it will be seen that the insideform-rollers 49 are dropping-rollers and are carried by suitable arms111, which are pivoted or may be caught on the shaft 110 of theform-rollers 48, the form-rollers 49 being mounted on suitable shafts112 for this purpose. The form-rollers 49 are kept in fixed contact withthe distrihitting-rollers 470 by means of springs 113. On the ends ofthe shafts 110 are arranged suitable lingers 120 or 122, as shown inFig. 3, and fixed to each end of the main frame are suitable cam-arms121-and 123, and the cam-arms 121 and 123 and their coacting fingers 120and 122 are arranged in different planes, whereby the fingers 120 willnever coact with `the arm 123. By means of these cam-arms when thecylinders are at their extremes in either direction the insideform-rollers of the cylinder that is outstandingy over an inkingapparatus will be depressed to positively engage thedistributing-cylinders 43 and 44, and as these distributing-cylinders 43and 44 are rotated the form-rollers 49 will be rapidly turned and aquantity of ink will be taken up' by the same. Then when. the cylindersstart to move back over the bed the springs will pull t-he form-rollers48 against the distributingd rollers 470, and thus the ink will be takenup also by the form-rollers 48, which bear against thedistributing-rollers470, whereby ink can be taken by each set ofdistributingrollers on each side of one of the cylinders when thecylinders reverse, as shown. By this mechanism a very simple andefficient inking apparatus is provided, lwhich will give a great andnice distribution and with which the press can be rapidly run. t

It is necessary in the operation before described to use a ratchet orequivalent mechanism, so lthat the oscillatory motion given t pinion 62will transmit an intermittent motion in the same direction to thegear63. To do this, the ratchet mechanism, such as is substantially shown inthe patent to Kidder, before referred to, may be used, and the way I mayarrange the same is as follows: A stud 130, having a suitable head 131,is fastened to the main frame by the nut 132. The pinion 62 has asuitable chambered-out sleeve 136, and the gear 63 has a similarchambered- IIO pin is a suitable shoe or pawl 135, which is ion 62 isturned in one direction the shoe or pawl 135 will cramp and will turnthe gear 63; but when the pinion 62 is turned in the other direction theshoe or pawl will not tend to cramp, but will slide loosely in thesleeve 134, and thus will not affect gear 63.V

The operation of my machine thus organized is apparent, and is asfollows: The web is slowly unwound from the roll F, and as thel` A sameis unwound it is looped up by the roller 8. YWhen the cylinders have'finished their printing stroke in either direction, the rollers 22 and23 will be quickly revolved, the brake 13 at this instant being removedfrom the roller 12, whereby -the slack paid out to the looping-roller 7will be pulled through the press, and the cylinders can then move back.to print the next sheet; but'during the printing operation the brakefl3will Atightly bite the Vroller 12, and will thus prevent the drag on theweb in the press from affecting the action of the looping-roller. thusdelivered forward by the intermittentlyoperated rollers 22 and 23 .willbe cut off into sheets bythe knives 25 and 26, will be folded by thefolding mechanism, and delivered by the fly onto the slowly-runningtapes 50.

By the mechanism previously described it I will have been noted that therollers 14 and 17 are continuously and rapidly revolved -to draw the webforward; but when the web is held by the brake 13 these rollers 14 and17 will simply loosely pull on the web and will not affect its action.In some cases I do not intend to drive the rollers 2O and 21continuousl'ygbut I prefer in most cases to do so, because by slightlypulling the web forward any slack that may occur beyond the brake willbe quickly taken up and will not affect the printing operation. Byhaving these guide-rollers 14, 17, and 20.continuously revolving, whenthe brake 13 is released and the rollers 22 and 23 started the web willbe very quickly moved, as the same will not have to be strained itsentire length before the same will be started, and this adds greatly tothe quick operation of the web. The rollers 20 and 21 do not tightlybear against each other, but the web runs easily between the same, sothat they can turn without pulling the web forward sufficiently hard tobreak the same.

It will be seen that when the cylinders are at their left-hand extremethe form-rollers near the impression-cylinder A will receive theirsupply of ink, and that when the impression-cylinders are in theirright-hand extreme the form-rollers near the impression-cylinder B willreceive their supply of The web ink. Thus only two fountains are neededfor the entire machine, and also it will ybe seen that the form-rollersare arranged on eachside of each impression-cylinder. `This operationwill serve to evenly ink the forms,where by both impressions will be thesame; Thus,

for example, take the case of the sheets printed by theimpression-cylinder A. In the position shown the cylinder has j ust beenmoved to the left, the web has just been fed forward, and the impressioncylinder is now started on its movement to the right.` On the previousmovement to the left the right-hand form-rollers 48. and 49 will haveinked the form, and now the right-hand form-rollers have just .receiveda new supply of ink and will thus again ink the form as theimpression-cylinder A prints on its right-hand movement. As the cylinderAfmoves tothe right the ink that has just been taken up by the left-handform-roller 49 will be spread on-the `form by the lleft-handform-rollers 48 and 49,

andwhen the impression-cylinder A moves again to the leftthe-left-hand.form-rollers 48 and 49 will pass back over the form on thebed C, and thus the form-rollers on each side of the impression-cylinderwillrun twice over the form before the impressionistaken in eitherdirection, and as two form-rollers are used on each side of theimpression-cylinder a very nice distribution is obtained.

A further description of the detailed parts is not thought necessary.

The details herein shown and claimed may be applied to other forms ofpresses than that illustrated, and especially some of them may beapplied to a forlnof press with the beds arranged one over the other.
